TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES A. McGLELLAND, of Vernon, in the county of Jehnings, and State of Indiana, have invented a new, and useful Device for Conveying Shavings and Dust from Planers and other Wood-Working Machines to Furnaees,'or any other desired place; and I do hereby'declare that the following is a, full, clear, and exact description thereof, which will enable others skilled in the art to niakc and use the same, reference being had to the accompanying drawings, formingpart of this specification, in which v Figure 1 is a side view of my invention, partly'in section.

Figure 2, a plan or top view of the same.

Figure 3, a vertical section of the same, taken in the line a: x, fig. 2.

Similar letters of reference indicate corresponding parts This invention nelates to a new and useful device for conveying shavings, "dnst, &c., to furnaces, or any other desired place, and is designedmore especially to be applied to wood-working machines, 8cm, for the purpose of elfectually removlng'all dust and shavings from; the saine, and Forces them into the furnace,- desired A represents a frame, which may be constructed irijany proper manner to support the working parts, and 13 represents a cylindrical case, within which, on the same shaft C, there are placed two fans, D D, one above the other, and divided by a horizontal partition, E, as shown clearly in fig. 3.- I

The uppeufan D is considerably larger than the lower one, D; The latter is supplied-with air througha tube,D y Y F represents a curved spout, one end of which communicates with the upper. part of the fan-case B,in

which'the fan D is enclosed, the other end of F extending down so as to be capable of'being placed in such" position with the machine to which it is applied as to suck up therefrom the shavings and dust as rapidly as they are made.

' G is a spout, one end of which eomrnunieateswitl the upper part ot' the fan-case B. The spout G is curved, and its opposite end extends down and communicates with a furnace, as shown in red in fig. 1. Y

H is an air-escape pipe, which communicates with the spout G, and has a valve, I, in its upper part. The shaft or axis of this valve has a crank, a, at one end, to which a rod, 6, is attached, the lower end of therod 6 being connected to a cranlgc, on the axis,'a valve, J, in spout G. I I

K is a spout, one end of which communicates with the lower part of the fan-case B, which encloses the fan D, an l-the opposite end communicates with the spout G, back of the valve J, betweenitand the escape-pipe H, (see fig. I.)

L is a spout, one end of which communicates with G, at OZ, when the valve J is open' the opposite end, e, of said spout being open: The operation is .as follows, viz: 7 Motion is given the fan-shaftC by belts or gearing arranged in any suitable way, and-when it is designed to feed the shavings or saw-dust to the furnace, the valve J iscloscd over the opening at, and the valves 1, in H, opened, as shown in fig. 1,both valves being adjusted simultaneously by actuating the rod 6.

The fan D causes a suction-blast in F, and draws up from the planing or other machines the shavings and saw-dust into the upper part of case B, the am expelling them th'rough'the spout G, direct into the furnace,

the pipe H admitting of the escape of some of the air, so as not to obstruct or interfere with the draught of furnace.v

When it is not desired to feed the furnace with the shavings or saw-dust, the valve J is opened and the valve I closed, and the shavings orsaw-dust will be expelled through the spout L, at e', outside the building orlshop, 7

During the time "the shayings or saw-dust are expelled from spout L, the small fan D forces a blast through the spout'K, into G, andQprevents any sparks beingdrawn up into Gfrom the 'iuruace. I Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The application of a suction and blast-fan to planing, circular saw, sand-belt, or other wood-working machinery, when arranged in the manner shown, or in an equivalent way, to draw the shavings or saw-dust from the machine and feed them to a furnace or dischaige them from the building or shop, substantially as set forth.

2. The arrangement of the two fans D D,spouts G K L F, and the valves I J, to operate substantially as and for the purpose specified.

3 The air-escape pipe H, in combination with the spouts G K L F, and valves J I, all arranged foijoint operation, substantially as and for the purpose set forth.
